All I know is I like how the 295's look compared to the 305's and I like that I can turn all the way in both directions and go over dips/bumps without worrying about rubbing the lip/liners whereas with 305's on the Tahoe I had to cut up/heat and bend the fender liners and semi roll the rear fender lips to clear them and still got a little tire rub.. The difference in width between the two might be minimal but it's enough to make a difference when it comes to obstruction..
